We tried a different brand of fertilizer this year- the rest is history.

After 6 days some serious brown spots have emerged. I fertilized on the same setting as usual, but got a much different result. Obviously I bare the responsibility for this, but is there anything to be done? It had been raining a lot. Is constant watering any help? It appears to not have gotten the long, but a few key areas which may have overlapped and got double treated. Not good! Help!

had it rained before you fertilized or after? Most fertilizer needs to be planted on early morning dew grass to give it something to cling to and immediately watered in. I have been in trouble when I hoped for rain, it never did and I was too late watering. Did you fertilize in the heat of the day? just don't cut it too short, water well once a week if it doesn't rain and hope for the best. Depending on the type of grass you have it is too late to plant anything new- wait till fall if it doesn't recover by then.

sometimes I get brown spots at the end of rows where I tary turning around or overlap.

no kudzu:
You're refering to fertilizer containing some type of pesticide, typically broadleaf weed control, but also mixing two seperate sets of instructions. Fertilizer with weed control is applied to damp lawns so that it sticks to the plants, it should not be watered in. Fertilizer by itself is better applied to a dry lawn and watered in after application.
As to the original question, you can try a couple things. Water, water, water - not to the point of runoff, but keep the lawn wet. Another help is to apply ground charcoal to the places burned by the fertilizer. If the lawn doesn't eventually come back, you may have to scratch up the brown areas and reseed.

Drench. Gypsum might help.
